Learn the major structures of the lungs and airways with this simple anatomy guide. Review the trachea, carina, bronchi, and lungs for class, quizzes, and exam prep.
The lungs are the main organs of the respiratory system. Their job is to bring oxygen into the body and remove carbon dioxide. Air travels through the upper airway, down the trachea, through the bronchi, and into the lungs where gas exchange takes place.
Learning lungs anatomy helps students understand breathing, airway structure, oxygen delivery, and respiratory function. It is especially useful for anatomy students, nursing students, TEAS review, and general healthcare exam preparation.
The trachea is the main airway tube that carries air from the throat toward the lungs.
The carina is the point where the trachea splits into the right and left main bronchi.
The right main bronchus carries air from the trachea into the right lung.
The left main bronchus carries air from the trachea into the left lung.
The right lung is larger and typically has three lobes.
The left lung is slightly smaller to make room for the heart.
Understanding lungs anatomy supports learning about breathing, oxygenation, airway function, and common respiratory conditions. It also helps students connect anatomy with clinical topics like wheezing, shortness of breath, pneumonia, and airway obstruction.
